Турнир "ФБ-6" -> Tournament "The Final Battle - 6"

Congratulations. What would have been the outcome if she had the Cloak of Renunciation?

Most likely, Nelk's higher stats and her weapon specialist ability would have made the difference. Besides, she had a golden bow.

Did Tyrannus have the red orb equipped in the final battle?

Yes. But there's a nuance: the prayer from the Haven faction works with the red orb, but not with the cloak. That's how it is.
